My app is a multi-views application, it has two views, here I named them view1 and view2, and only view2 has a toolbar;

Now let me say the problem I met, start my application from menu, view1 is default view, so it will be shown, and no toolbar inside it; Then switch to view2, toolbar was be shown as well now, by far, everything is okay;

But when I switch back to view1, the toolbar still can be seen, even I tried to call Toolbar()->MakeVisible( EFalse ) or StopDisplayingToolbar() in view2's DoDeactivate() function; And this problem only appear on device, emulator is ok.

Do you know why? And welcome any idea how to solve my problem, thanks in advance!!
